WARPER LINTTV CLEANER.

Application filed November This invention relates to a pneumaticmechanism for maintaining a warper free from lint and fly at thoseplaces where a collection of lint and fly is injurious to the operationof'the warper. 1 T

The invention has for its main object to provide means for blowing adraft of air along the dents of the warper combs toward the free ends soas to maintain the combsfree from fly and lint.

The invention has for its further object to provide a warper lintcleaning mechanism of the pneumatic type which will be simple. practicaland eflicient in its operation and prevent the collection of fly andlint particularly on the warper com s.

These and other objects and features of the invention will appear morefully from the accompanying description and drawings and will be pointedout in the claims.

As the invention only has to do with the lint cleaning feature and asthe general construction and operation of warper-s are well known andfamiliar to those skilled in the art, and as the invention may beapplied to various types of warpers, it is'suflicient here to illustrateonly those parts of a single type of warper with which the invention isparticularly concerned.

combs.

Fig. 3 is a detail in side elevation, broken away, of a portion of awarper similar to that shown in Fig. 1, but showing a slightly differentform of combs with the blowers arranged to blow the air along the dentsand toward the freeends thereof.

In a warper, the warps are taken usually from a creel and wound on awarp beam. Such warpers are provided with combs for separating andguiding the warps, with drop wires for stopping the warper if a warpbreaks and with other instrumentalities upon which moreor less fly andlint is likely to collect, and this is particularly true of the warpercombs which are usually located at the rear and front of the warper.

The warper illustrated in Figs. 1 and 2 1, 928. Serial No. 316,423.

comprises side frames 1 and is shown as V supporting suitable guide orlease rods 2, a rear combr3, a bank of drop wires'4. a

front comb 5 and a suitable front guide roll 6. The warps 7 are laidfrom the creel through and over these various instrumentalities andwound up on the warp beam 8 mounted at the front of the warper.

The combs 3 and 5 are made up of a transverse row of dents 9 hereinshown as round wires having vertical shanks with the-p01 tions 10inclined upwardly and away from V a vertical plane extending laterallyof the warper. J In both combs the inclined portions 10 of the dents areshown as extendrection oftheir inclination, thus maintaining them freeand clear of fly and lint and blowing any fly and lint that tends tocollect-thereon well forwardover the front of the warper. r I

The nozzle at the front of the warper is shown as a box-like structure11 mounted on the frame and extending transversely of the warper in therear of the front comb and having its mouth 12 open at the base of thedents 9 and inclined in the same direc- Another nozzle 13 of similarstructure, shape and position is shown at the rear of the rear comb.

Branch conduits 15connect the main conduit and the nozzles ateach side and are preferablyso. arranged that they open into the nozzles at regular intervalstransversely or laterally of the warper.

Air under pressure is supplied to the main conduit and thence to thenozzles and may be obtained from any suitable source. As illustrated,ablower l6 is mounted at the rear of the warper and connected by a pipe17 to the main conduit, but any suitable means mayb provided for thussupplying the required air under pressure.

The construction. illustrated. in Fig. 3. in.- volves the. sameprinciples,. but; a slightly different form of comb. Herein the combs 18and 19 at the front and the back: of thewar'per comprise straight dents20, but the combs as a whole areshownsetiat an angle" so as topointupwardly and forwardly. In this case the nozzles 21 have their mouths 22extending close to andparallel with the dents so that the draft of airissuing therefrom is projected along the dents to ward their free ends.The relation of the nozzle to the combs is a most important feature andit may not even be necessary to incline the dents because with the: airdraft projected along the dentstowardtheir' free ends, the combs willbe: cleared of fly and lint and the draft caused by the moving warps,especially with the high. speed 4 It will thus be seen'that a strongvairis blown from each nozzle along the warperdentstoward the free endsthereof in 7 an upwardly and preferably in. atransversely inclineddirection. This-renders it imposand as it has no moving. parts, it does.not
